VAGINAL SPECULU'M.

Application filed May 24,

yThis invention relates to a vaginal speculum and it has for its object, to improve the construction of the speculum so tha-tit is securelyheldin the-vagina and not pushed out at the least pressure exerted bythe patient. Even if the vagina is spread out as much as possible, aspeculum of commonly used type might be pushed out by the contraction ofthe constrictor cmmi muscle so far that it has to be readjusted. Thespeculum of commonly used construction is therefore not capable to serveas substitute for an assistant surgeon. In the speculum of known typethe entrance opening 1s comparatively narrow and the interior of thevagina is only dimly lighted by the day light so that the operation isgreatly impeded. I

It has been proposed to electrically light the speculum whereby;however, the incon'y venience is not obviated that the interior of thevagina and especially the uterus are not easily accessible.

The speculum, according to this invention, is specially constructed fromthe pointl of view to make it adapted to the structure of the femalepelvic-bone. The vagina extends anatomically from the entrance to theuterus underneath the acute angled pelvic arch. According to theinvention the downwardly directed inclined arms of the pelvic arch areutilized as supports for holding the inserted speculum in its spread-outposition so that it can be moved from this position neither by pull norpressure, no pain being caused to the patient. rlhe uterus can bebrought, with the aid of the improved speculum, into the most favorableposition for opera-tions.

An embodiment of the invention is shown, by way of example, in theaccompanying drawing in which z Fig. 1 shows the improved speculum infront elevation.

Fig. 2 is a side elevation of Fig. l.

Fig. shows in front elevation a slightly modified form of constructionof the speculum shown in Fig. l.

Fig. 4 is a side elevation of Fig. 3.

The improved speculum consists of a siaft 1 the front end of which isbent at right angles and of curved cross section. The front portion isthickened to form a shield 2 the rear edge of which forms aperpendicular shoulder. In the shaft 1 a longitudinal yslot 3 isprovided, and a slotted 1926, Serial No. 111,399, and. in Germany June8, 1925.

slidable member 4 is placed upon this shut' i 1. In the front end of theslotted member 4, two arms 6, 7 are pivotally mounted with the aid of apivot screw l5, the inner end of which screw engages with the slot 3 ofthe shaft. The arms 6, 7 traverse each an eye 8, v9 fixed at the portionof the shaft where it" merges into the shield 2. The arms 6, 7 areoutwardly inclined from the pivot screw 5 and curved in forward andinward direcf ltion approximately at the point where the Yshield 2begins so that the front. portion of the arm stands -at right angles tothe rear portion. This front portion of the arms 6, 7 is bent againtwice at right angles at 10 shortly before the ball-shaped point 11. Athumb screw 12 screwed through the slot of member 4 into the body of theshaft 1 serves to guide said slotted member 4. The slotted member 4 isoutwardly bent at its lower end and carries a finger-plate 13..

A speculum constructed, especially for operatlons, is shown in Figs. 3and 4. This speculum is of similar construction as the one, .shown inand described with reference to Figs. 1 and 2 with the exception,however, that the arms 6, 7 are shorter, the balls 11 sitting directlyupon the upwardly directed arm at 10. The bent front portion of theshaft 1 on which the plate-shaped portion behind the shield 2 is formedis plateshaped and has an aperture 14. Instead of an aperture anindentation of convenient shape might be provided in the plate-shapedfront portion of the shaft 1.

If the speculum is in the position of rest, the front portion and thebend 10 of the arms 6, 7 are located in the shield 2 or, in the speculumfor operations shown in Figs. 3 9

and 4, accommodated in the aperture 14 or indentation of theplate-shaped portion of the shaft.

To insert the speculum Vinto the vagina the thumb screw 12 has to beloosened so that, after the insertion, the slotted mem-V ber 4 can bepushed forward by a slight pressure exerted upon the finger-plate 13, sothat the arms 6, 7 spread out, and the bent portions 10 grip' behind thedownwardly directed arms of the pelvic arch so that the speculum is heldsecurely in the vagina, the shield beinO pushed into the mucous membraneon the rear wall of the vagina. The ball-shaped .points of the armsprotect the vagina against injury at the insertion of the speculum. A

I claim:-

1. A Vaginal speculum, comprising in combination a shaft serving ashandle and having a longitudinal slot, a shield at the front end of saidshaft standing at right angles to said shaft, a slotted member shiftablymounted on sai-d shaft, a screw bolt in the front end of said slottedmember and engaging with said slot 'of said shaft7 two eyes at the endof said shaft where it merges into said shield7 two arms pivot-ablymounted on said screw bolt and traversing each one of said eyes saidarms being curved forward so that the front parts are parallel to theshield, a bend at right angles being formed in the 4front part of eac-harm said bends being designed to grip behind the downwardly directedarms of the pelvic arch of the Vagina, and ball-shaped points on saidfront ends.

2. A vaginal speculum, comprising in Combination a shaft serving ashandle and having a longitudinal slot, a shield at the front end of saidshaft standing at right angles to said shaft and a central apen turebehind said shield, a slotted member shiftably mounted on said shaft, asere" bolt in the front end of said slotted member and engaging withsaid slot of said shaft, two eyes at the end of said shaft where itmerges into said shield, two arms pivotably mounted on said screw boltand traversing e-aeh one of said eyes said arms being curved forward sothat the front parts are parallel to said shield, a bend at right anglesbeing formed lin the front part of each arm, said bends being designedto grip behind the downwardly directed arms of the pelvic arch of thevagina and to be accommodated in said aperture behind said shield if thearms are in the position of resta and ballshaped points on said frontends.

In testimony whereof I aflix my signature.
